Aquaforest TestPro Calcium is designed to quickly measure the concentration of Calcium in marine water. Calcium plays an important role in many biological processes, e.g. takes part in the construction of hard coral’s calcium carbonate skeleton. Calcium levels should be analysed regularly, together with other critical water parameters like Alkalinity and Magnesium. Recommended Calcium level should be maintained in the range between 400-450 mg/l (ppm). Test Kit contains sufficient reagents to perform approx. 55-60 separate tests within that range.

Aquaforest TestPro Magnesium is designed to quickly measure the concentration of Magnesium (Mg) in marine water. Magnesium plays an important role in many biological processes, e.g. takes part in the construction of hard coral’s calcium carbonate skeleton. Due to it’s unique chemical properties it has significant impact on seawater buffering capacity, and also prevents excessive precipitation of calcium carbonate on aquarium equipment. Adequate level of Magnesium is crucial in maintaining proper Calcium and Alkalinity balance in reef aquaria. Mg levels should be analysed regularly, together with other critical water parameters like Calcium and Alkalinity. The concentration of Magnesium in natural seawater is between 1260-1500 mg/l (ppm). Test Kit contains sufficient reagents to perform approx. 55-60 separate tests within that range.

Ideal for commercial use. Includes a carrying case with belt clip.
Highly efficient and accurate due to its advanced microprocessor technology.
Hold Function: saves measurements for convenient reading and recording.
Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries.
Measurement Range: 0-9990 ppm. From 0-999 ppm, the resolution is in increments of 1ppm. From 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking 'x10' image.
Built-in digital thermometer
Display: large and easy-to-read LCD screen.
Factory Calibrated: our meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver.
Also available in "x10" mode: reads in increments only of 10 ppm (0-9990 ppm). Learn More

NYOS REEFER test kits - taking measurements at the laboratory level at an attractive priceWater properties as close to nature are the key for every aquarium's success. However, monitoring relevant parameters in seawater is difficult due to numerous interfering ions. Therefore, test kits considering the specific characteristics of seawater are needed to analyse the water precisely.

Using The Test

The test kit itself is about in the middle of the pack in terms of complexity. It is not as easy as many kits, but not as complicated as certain kits. There are reagents present for at least 10 measurements, and in most cases where boron is not excessively high, many more. The process is roughly as follows (detailed directions are available from Salifert at their [web site][23]):

Use a syringe to draw up some tank water.

Add 2 liquid reagents and mix. The solution is green

Split the batch in half with a syringe.

Add a solid to one half (which changes the color to yellow).

Add one of the liquid reagents dropwise until the colors match (a green).

Each drop of titrant amounts to 0.5 ppm boron. I could easily match the color to within 2 drops, so the uncertainly of the titration itself is about +/- 0.5 ppm or so. The color continues to change on overshooting the titrant, so it is clear (at least to me) when enough was enough.

Be sure to carefully follow the directions about which reagent to titrate with. While the directions are perfectly clear, I actually titrated with the wrong one on two different occasions, resulting in the color never changing.

One other comment. The first kit that I obtained was identical to the ones that I tested, except that it had apparently been sitting around a store for a long time (years perhaps). One of the reagents (B3) can go bad by reacting with atmospheric carbon dioxide, and it had done so in my kit. Habib Sekha has indicated that when that happens, the reading for boron can rise. In my case, it rose so much that I never found a color endpoint, indicating very, very high boron.

Calcium is a major constituent of calcareous algae, skeletal material of hard corals and the skeletal needles of soft/leather corals. Calcium also fulfills many biological functions. These processes result in depletion of calcium. Quite often a too low calcium concentration retards growth of corals and calcareous algae. NSW (Natural Sea Water) contains 400 - 450 mg/L calcium. This is also the value we should strive for. Learn More
